#       bounce 5
# SUMMARY
#       Postfix bounce message template format
# SYNOPSIS
#       \fBbounce_template_file = /etc/postfix/bounce.cf\fR
#
#       \fBpostconf -b\fR [\fItemplate_file\fR]
# DESCRIPTION
#       The Postfix \fBbounce\fR(8) server produces delivery status
#       notification (DSN) messages for undeliverable mail, delayed
#       mail, successful delivery or address verification requests.
#
#       By default, these notifications are generated from built-in
#       templates with message headers and message text. Sites can
#       override the built-in information by specifying a bounce
#       template file with the \fBbounce_template_file\fR configuration
#       parameter.
#
#       This document describes the general procedure to create a
#       bounce template file, followed by the specific details of
#       bounce template formats.
# GENERAL PROCEDURE
# .ad
# .fi
#       To create a customized bounce template file, create a
#       temporary
#       copy of the file \fB/etc/postfix/bounce.cf.default\fR and
#       edit the temporary file.
#
#       To preview the results of $\fIname\fR expansions in the
#       template text, use the command
#
# .nf
#           \fBpostconf -b\fR \fItemporary_file\fR
# .fi
#
#       Errors in the template will be reported to the standard
#       error stream and to the syslog daemon.
#
#       While previewing the text, be sure to pay particular attention
#       to the expansion of time value parameters that appear in
#       the delayed mail notification text.
#
#       Once the result is satisfactory, copy the template to the
#       Postfix configuration directory and specify in main.cf
#       something like:
#
# .nf
#       /etc/postfix/main.cf:
#           bounce_template_file = /etc/postfix/bounce.cf
# .fi
# TEMPLATE FILE FORMAT
# .ad
# .fi
#       The template file can specify templates for failed mail,
#       delayed mail, successful delivery or for address verification.
#       These templates are named \fBfailure_template\fR,
#       \fBdelay_template\fR, \fBsuccess_template\fR and
#       \fBverify_template\fR, respectively.  You can but do not
#       have to specify all four templates in a bounce template
#       file.
#
#       Each template starts with "\fItemplate_name\fB = <<EOF\fR"
#       and ends with a line that contains the word "\fBEOF\fR"
#       only. You can change the word EOF, but you can't enclose
#       it in quotes as with the shell or with Perl (\fItemplate_name\fB
#       = <<'EOF'\fR). Here is an example:
#
# .nf
#           # The failure template is used for undeliverable mail.
#
#           failure_template = <<EOF
#           Charset: us-ascii
#           From: MAILER-DAEMON (Mail Delivery System)
#           Subject: Undelivered Mail Returned to Sender
#           Postmaster-Subject: Postmaster Copy: Undelivered Mail
#
#           This is the mail system at host $myhostname.
#
#           I'm sorry to have to inform you that your message could not
#           be delivered to one or more recipients. It's attached below.
#
#           For further assistance, please send mail to postmaster.
#
#           If you do so, please include this problem report. You can
#           delete your own text from the attached returned message.
#
#                              The mail system
#           EOF
# .fi
# .PP
#       The usage and specification of bounce templates is
#       subject to the following restrictions:
# .IP \(bu
#       No special meaning is given to the backslash character or
#       to leading whitespace; these are always taken literally.
# .IP \(bu
#       Inside the << context, the "$" character is special. To
#       produce a "$" character as output, specify "$$".
# .IP \(bu
#       Outside the << context, lines beginning with "#" are ignored,
#       as are empty lines, and lines consisting of whitespace only.
# .PP
#       Examples of all templates can be found in the file
#       \fBbounce.cf.default\fR in the Postfix configuration
#       directory.
# TEMPLATE HEADER FORMAT
# .ad
# .fi
#       The first portion of a bounce template consists of optional
#       template headers.  Some become message headers in the
#       delivery status notification; some control the formatting
#       of that notification. Headers not specified in a template
#       will be left at their default value.
#
#       The following headers are supported:
# .IP \fBCharset:\fR
#       The MIME character set of the template message text.  See
#       the "TEMPLATE MESSAGE TEXT FORMAT" description below.
# .IP \fBFrom:\fR
#       The sender address in the message header of the delivery
#       status notification.
# .IP \fBSubject:\fR
#       The subject in the message header of the delivery status
#       notification that is returned to the sender.
# .IP \fBPostmaster-Subject:\fR
#       The subject that will be used in Postmaster copies of
#       undeliverable or delayed mail notifications. These copies
#       are sent under control of the notify_classes configuration
#       parameter.
# .PP
#       The usage and specification of template message headers is
#       subject to the following restrictions:
# .IP \(bu
#       Template message header names can be specified in upper
#       case, lower case or mixed case. Postfix always produces
#       bounce message header labels of the form "\fBFrom:\fR" and
#       "\fBSubject:\fR".
# .IP \(bu
#       Template message headers must not span multiple lines.
# .IP \(bu
#       Template message headers do not support $parameter expansions.
# .IP \(bu
#       Template message headers must contain ASCII characters only,
#       and must not contain ASCII null characters.
# TEMPLATE MESSAGE TEXT FORMAT
# .ad
# .fi
#       The second portion of a bounce template consists of message
#       text. As the above example shows, template message text may
#       contain main.cf $parameters. Besides the parameters that are
#       defined in main.cf, the following parameters are treated
#       specially depending on the suffix that is appended to their
#       name.
# .IP \fBdelay_warning_time_\fIsuffix\fR
#       Expands into the value of the \fBdelay_warning_time\fR
#       parameter, expressed in the time unit specified by
#       \fIsuffix\fR, which is one of \fBseconds\fR, \fBminutes\fR,
#       \fBhours\fB, \fBdays\fR, or \fBweeks\fR.
# .IP \fBmaximal_queue_lifetime_\fIsuffix\fR
#       Expands into the value of the \fBmaximal_queue_lifetime\fR
#       parameter, expressed in the time unit specified by
#       \fIsuffix\fR.  See above under \fBdelay_warning_time\fR for
#       possible \fIsuffix\fR values.
# .IP \fBmydomain\fR
#       Expands into the value of the \fBmydomain\fR parameter.
#       With "smtputf8_enable = yes", this replaces ACE labels
#       (xn--mumble) with their UTF-8 equivalent.
# .sp
#       This feature is available in Postfix 3.0.
# .IP \fBmyhostname\fR
#       Expands into the value of the \fBmyhostname\fR parameter.
#       With "smtputf8_enable = yes", this replaces ACE labels
#       (xn--mumble) with their UTF-8 equivalent.
# .sp
#       This feature is available in Postfix 3.0.
# .PP
#       The usage and specification of template message text is
#       subject to the following restrictions:
# .IP \(bu
#       The template message text is not sent in Postmaster copies
#       of delivery status notifications.
# .IP \(bu
#       If the template message text contains non-ASCII characters,
#       Postfix requires that the \fBCharset:\fR template header
#       is updated.  Specify an appropriate superset of US-ASCII.
#       A superset is needed because Postfix appends ASCII text
#       after the message template when it sends a delivery status
#       notification.
